Per the very first reply on their thread discussing it in their forums, which I linked directly to for the post title:
We’ll NEVER require any verification or identification from the user.
However, what’s gonna happen should the attempts to age-gate the XDG portal screw over alt-init distros like Artix too? My guess is maybe they start blocking regions which force age gating like Arch Linux 32 is doing.


Based on what? They have specifically addressed the issue and it does not read like they’re eager to have this forced on them by state laws.
